In the Spine editor, the "Audio path" for an event is not designed to be changed per keyframe in the timeline. The audio path is set for the event as a whole, and it remains constant across all keyframes where the event is triggered. This is different from properties like Integer, Float, String, Volume, and Balance, which can be adjusted for each keyframe. If you want to play different audio samples for each instance of the event, you would need to create separate events for each audio sample you want to use. Each event can have its own audio path, and you can then trigger these different events at the desired keyframes in your animation.
